(Cl. 189-65) Myinvention relates to a new and useful improvement in a windowconstruction and particularly that type of window which embodies awindow frame having a pair of window sashes mounted therein with theframe forming portions formed preferably from metal.

It is an object of the present invention to provide a windowconstruction of this class which will be simple in structure, economicalof manufacture, durable, light, easily and quickly assembled and highlyeificient in use.

Another object of the invention is the provision in a windowconstruction of a window frame or a Window sash each having oppositelydisposed side rails, a top rail and a bottom rail, with the side railsjoined to the adjacent ends of the top rail and the bottom rail by apair of L-shaped members secured in position by a boss driven into theL-shaped members from the rail members.

Another object of the invention is the provision of a window framehaving a window sash formed therein of slightly less width than thewindow frame and each part being provided with overlying sealingportions for sealing against entry of air between the window frame andthe sash.

It is another object of the present invention to provide in a windowconstruction of this class, having a pair of slidable sashes, a springclip adapted for engaging both of said sashes and pressing same intoclose engagement with the window frame and adapted, upon removal of thelower sash, for engaging beneath the upper sash and retaining it inposition.

Another object of the invention is the provision of a pair of windowsashes slidably mounted in a window frame so constructed and arrangedthat the upper rail of the lower sash and the lower rail of the uppersash will inter-engage to provide a connection whereby inward or outwardmovement of the sashes relative to the frame will be prevented, eachsash cooperating with the other for resisting any thrust directedinwardly or outwardly of the sashes.

Another object of the invention is the provision of a screen havingoppositely disposed side rails and a top and a bottom rail constructedso that they are held together relatively to each other by bossesembedded in L-shaped retainers.

Other objects will appear hereinafter.

It is recognized that various modifications and changes may be made inthe detail of structure illustrated without departing from the inventionand it is intended that the present disclosure shall be considered butthe preferred embodiment.

Forming a part of this application are drawings, in which:

Fig. 5 is a fragmentary elevational view of a corner of the window frameslightly enlarged,

Fig. 6 is a sectional view taken on line 6-6 of Fig. 5,

Fig. 7 is an elevational view of the screen used with the invention,

Fig. 8 is a sectional view taken with a part broken away,

Fig. 9 is a sectional view taken on line 99 of Fig. 7 with a part brokenaway,

Fig. 10 is a slightly enlarged sectional view taken on line 10-19 ofFig. 7.

As shown in the drawings, the window frame comprises the oppositelydisposed side rails 15 and 16, the top rail 17 and the bottom rail 18.It is intended that these rails be formed from metal, such as aluminumor the like, and each of the rails is of similar construction in crosssection so that a description of one will suffice for all.

As clearly shown in Fig. 2, Fig. 3 and Fig. 6, each of the rails isprovided with a channel 19 having a bottom on line of Fig. 7

0 2i) and a side wall 21 spaced apart from the main body of the rails15, 16, 17 or 18. Projecting inwardly from the part 21 is a rib 22 inspaced apart relation from a rib 23, projecting inwardly from the mainbody of the Positioned in the channel 19 at the corners is a pair ofL-shaped members having the legs 24 and 25, 26 and 27. As shown in Fig.5, one of these legs extends in a channel in the side rail and the otherleg extends in a channel in the bottom rail. A similar constructionwould be provided at the top rail. When these rails are assembled, sothat the adjacent ends of the top and side rails are in engagement andthe adjacent ends of the bottom and side rails are in engagement withthe L-shaped members positioned as shown in Fig. 6, a tool is used todrive inwardly the bosses 28, shown in Fig. 6, which are forced into thebody of the L-shaped members, thus securing the rails of the frame infixed relation. Experience has shown that this provides a very sturdyand rigid construction. It is believed obvious that it is a constructionwhich lends itself to quick assembly. As clearly shown in Fig. 3, thereis extending inwardly from the portion 29 a flange 29. This extendsaround the frame and serves as an abutment for a sash which is adaptedto be mounted in the frame.

In Fig. l I have shown a pair of sashes mounted in the frame. The uppersash has a pair of side rails, denoted generally by the numerals 31 and32, a top rail 34 and a bottom rail 35. The lower sash is provided witha pair of side rails 37 and 38, a top rail 36 and a bottom rail 39. Allof these rails are constructed similarly in cross section, excepting thebottom rail 35, so that a description of any of the other rails willconstitute a description of all of the others. As shown in Fig. 2 therails of the lower sash are provided with a channel 40, in which isadapted to engage a of a pane of glass 51. Extending laterally from theside wall 41 of the channel 40 is a flange 42, which is angularly turnedto provide the wall 43 to form a channel 44,

in which engages one leg of a pair of L-shaped members- 45 and 46. TheseL-shaped members are located at the corners of the sash frame and aresecured in position in the same manner as the L-shaped members of thewindow frame, which have already been described. In this manner the fourrail forming portions are securely fastened together at their meetingends after the pane of glass has been inserted in position. Extendingoutwardly from the member 41 is a rib 47 in the rib 48 extendinginwardly from the wall 43. These ribs serve to properly locate theL-shaped members 45 and 46 in position and retain them frame 50 securedaround the edgesalignment with.

in position until the is a flange 53 which overlies the wall of thechannel 40.

It will be noted that when the two sashes are in proper relative closedposition the member :53 serves 'as a seal and the .member 54 also servesas ;a seal ;for preventing passage of air between the upper rail ofthelower sash and the lowerrail of -thelupper sash. It will also benoted that a tliru sttending to move either of these sashes inwardly oroutwardlyis resisted by the other sash. v Move- 'out'wa rdlyc'oiild' nottake place, of course, because of'tlreengagem'ent of the sa'shes' withthe flange '29. In-

ward movement of the sashes is prevented by the spring cli s.

shownin Fig.1, a spring body 55 is secured to the window frame andextended outwardly and extending longitudinally 'ofth e window frame isa pair of resilient 56 and 57, each of which is adapted to engageagainst jthe side rail of the sash. As shown in Fig. 1,

mounte d'at the location of the meettongues one er these clips is ingo't the lower sash with the upper sash and one is mounted adjacent theupper end of the window frame.

7 Consequently, any inward thrust delivered to either of the frames atthe lower rail of theupper sash would be resisted by measure bbdy of thespring clip.

Secured to the upper rail of the Window frame is a spring clip "60 whichis adapted to engage theouter face of---a window screen place dthereunder, the lower edge of which wonld' -be engaged by a'tongue 59projecting outwardly fror'n'the'tongue 58. With this construction apersonzma-y use these two clips for retaining the screen storedadjacentjtlie window when the screen is not in use.

Swingably mounted on-the flange 21 of the lower rail of the'win'dowframe -is a pair of clips 61 formed from resilient material and havingan angularly directedltongne 62, providedhn its upper'face with a recess63. The clip 61, when rotated to the position shown in Fig. 1, 'willserve to overlie the lower rail of the lower sash and prevent inwardmovement of thelower rail of the lower sash, so that it cannot beremoved from the window frame. When these clips" are -turned'90 degreesin either'direction, so as to clear the lower rail and lower sash, thesash may bepulled iriwardl-y at its lower end by means of the loops64,-'which :are mounted thereon, and thus the lower sash may be removed.When the lower sash is removed the tongues 58 will swing inwardly to liebelow the lower rail of .the upper sash and prevent the upper sash fromsliding-downwardly. I

iWhen it is-desiredto open the window a slight distance thelmember 61may be turned 180 degrees and the loweredls'asli may then be swunginwardly, as shown in dotted lines in Fig 2, until-its lower edge snapsinto the recess 63; this waythe rower sash may be opened slightly, andheld firmly. in this slightly opened position, for ventilating purposes.H

In Fig. 7, and the sections taken thereon, I have illustrated'theconstruction of the screen used with the window eonstruetion. The screencomprises a frame having the oppositely disposed side rails 65 and 66,the bottom rail 67 'and'top'r'a'il 68. A'll of these rails areconstructed larly in cross section and a' description of one willsuffice for all. The main'bedy '69 of the rail is provided with achannel 10 from the walls of which are the inwardly projectingri'bs71'and 72, Positioned in this channel and engaging *tliejb'ottom thechannel, and also engaging ii'inafthefib 1' 1 is re: o L- shapedmembershaving the legs '73 and .74.

'shownin' Fig. '1 "the L shapedmembers are so'positionetl that one ofthe legs lies in the channel of a side rail and the other leg lies in achannel of a bottom or top rail. At the location there is punchedinwardly, from the opposite sides of the channel, the bosses 76, whichare driven into the material of the L-shaped legs 73 and 74, so that theside rails and the "top and botom rails are thus securely fastenedtogether. Formed in the body 69 is a channel or ram/e75 in which ispressed a bead 77 formed from plastic rubber or other suitable flexiblematerial to press the edges of the screen 79 intothe v groove and securethe screen in taut eonditien on thefr'ame. An overhanging lip 78servesto' engage this retaining strip 77 and retain it in position. Itis believed obvious that the construction of the screen frame may beeasily and quickly efiected and that the mounting of the screen thereonin a secure manner is easily and quickly accomplis'hed.

What I claim'is': U r I I 1.
